让步状语从句:
主要连接词:although (虽然)/ even if (though) (即使)/ while (尽管)后两个是考试的重点。no matter what… (= whatever无论…什么…) / no matter how… (=however, 无论怎样…) / whether…or not (不论…还是…)这是让步句考试的重点。
例如:
No matter what (或Whatever) may happen, we will not change our plan. (无论可能发生什么,我们决不改变计划。)
No matter how difficult (或However difficult) the journey may be, we will not change our plan. (不管路程有多难,我们决不改变计划。)
We should not worry her whether she is well or ill (或whether she is ill or not).(无论她身体好坏,我们都不应使她烦恼。)
注意:no matter what后面跟名词或名词性结构;no matter how后面跟形容词或副词,不要搞错;用了no matter what / no matter how就不能再用whatever / however.
5) 比较状语从句:
这是英语语法必考内容,要特别加以重视。
基本概念:两个比较级,三个或三个以上最高级。要对数字"2"特别敏感,试选择:
Of Mary and Jane, who is ______?
A. smart B.the smartest
C. more smarter D.the smarter
解题思路:很显然这是一道考形容词比较级的题目,从句子结构和选题A可以判断smart是个形容词原级,因此可以断定C的形式错了(重复比较,如不能说more happier 一样的道理)。B是最高级,但句中只有两个人Mary 和Jane,因此正确答案只能是D,这是一个较特殊的比较级句型,即the + 形容词比较级 + of (两个)。
比较级的主要句型:
(1) 原级比较:as +形容词或副词原级+ as, 否定式:not so (或as) +形容词或副词原级+ as
注意问题:as…as 之间的形容词或副词是否采用了原级;as…as 之间该用形容词还是副词;用as much as 还是用as many as
表示倍数时用下面结构, 如3倍:three times as …as…
例如:
The size of the island is about ______ that of this one.
A.three times as much as B.as three times much as
C.as three times greater than D.three times as big as
解题思路:B、C违反了上述句型规定,A、D的区别是size(大小 / 尺寸)是与much搭配还是与big搭配,D是对的。
(2) 比较级:more …than…
注意:
1) 比较形式是否正确,如是否有类似"more better"这样重复比较的错误;
2)两者之间是比较级,三者以上是最高级,看看是"两者"还是"三者或三者以上;
3)只有同类的人或物才能比较(可比性);比较不能包括"自己", 常用other表示排除。
例如不能说:
He is taller than any students in this class.
而应说:
He is taller than any other student(s) in this class.
4)修饰比较级的词有:much, even, far, by far, still, a lot, a bit 等,例如:
John did badly in the sports meet. I did even worse (than John did).
你能看出下句的问题吗?
His salary as a bus driver is more higher than a teacher. ( 他是个公共汽车司机,他的工资要比教师高。)
该句有两个大错1)high的比较级为higher,2)主语his salary(他的工资)而比较对象是a teacher,两者不可比,怎样的表达才是对的呢?请选择:
His salary as a bus driver is much higher ______.
A.in comparison with a teacher B.than a teacher
C.than a teacher's D.than that of a teacher's
正确答案是C,也可以写成than that of a teacher(请联系名词格的概念想一想)
最高级the most of +比较范围 / 最高级+名词+that (不是which)定语从句,例如:
This is the most interesting film that I have ever seen. (这是我看过的最有趣的电影。)
the more…the more…
The longer you wear glasses, the more you depend on them. (眼镜戴的时间越长越有依赖性。)
考试时,一般只要认准"the" 和比较级形式就不难判别。
其他表示比较意思的形式
A is superior / inferior to B(A 比B高级 / 低级)
注意:superior/ inferior前不能再加 more 或者less; 用to不是用 than.
例如:
Humans are superior to animals in that they can use languages to communicate.(人比动物高级在于人能用语言进行交际。)
prefer… rather than (宁可…而不…)
例如:
I preferred to stay out in the cold rather than spend the night there. (我宁可呆在外面受冷,也不在那儿过夜。)
Would rather…than… ……(用法和意思与上句型差不多)
6) 地点状语从句:
主要连接词:where / wherever / everywhere
注意地点状语从句中where与定语从句中关系副词where的区别与联系:
Put the book where it is. (把书放好,即"把书放在该放的地方。)
Put the book in the place where it is.
以上两个句子的意思是一样的,第一个句子是"地点状语从句",第二个句子是"定语从句"(详见"第四讲"),where作关系副词修饰the place。
